|Superficial palmar branch of radial artery|
Palm of left hand, showing position of skin creases and bones, and surface markings for the volar arches.
|Branches||superficial palmar arch|
|Latin||ramus palmaris superficialis arteriae radialis|
Running forward, it passes through, occasionally over, the thenar muscles, which it supplies, and sometimes anastomoses with the terminal portion of the ulnar artery, completing the superficial palmar arch.
This vessel varies considerably in size: usually it is very small, and ends in the muscles of the thumb; sometimes it is as large as the continuation of the radial artery itself.
